Description
Technical field
The present invention relates to a kind of deviation correcting device and method in diaphragm wall unit groove sector hole, be adapted to especially adopt percussive drill to carry out the interior correction of diaphragm wall unit groove sector hole of trenching construction.
Background technology
Adopt percussive drill to carry out, in diaphragm wall slotted eye building course, due to the inhomogeneities of soil layer, often causing slotted eye deflection, when slotted eye deflection exceedes code requirement, can workmanship be affected.In order to ensure workmanship, must correct deflection in hole.Traditional method for correcting error mainly contains: (1) backfills block stone or concreting in hole, and the method repeating pore-creating is rectified a deviation; (2) install deviation correcting device in aperture, by changing the direction of suspention drilling tool wire rope, the method for repetition pore-creating is rectified a deviation.At present, the one-tenth groove depth of diaphragm wall reaches more than 100m, and adopt traditional method for correcting error to rectify a deviation, effect is poor, does not even have correction effect, directly affects diaphragm wall workmanship.
Summary of the invention
In order to overcome the deficiency adopting traditional method for correcting error to rectify a deviation to diaphragm wall unit groove section, technical problem to be solved by this invention is to provide a kind of deviation correcting device and method in novel hole, rectifies a deviation to slotted eye.
The object of the present invention is achieved like this:
Deviation correcting device in a kind of diaphragm wall unit groove sector hole, it comprises bale handle, guiding and Deviation rectifier, bale handle is used for promoting deviation correcting device, guiding is guaranteed in correction process, drilling tool does not creep into along foramen primum, Deviation rectifier is used for changing the direction of drilling tool, guarantees bit cutting hole internal cause deflection and outstanding position.
Above-mentioned deviation correcting device adopts 10# i iron to be welded, and thick about 100mm, is about 5m, and its width is determined according to the wall thickness of diaphragm wall.
The above-mentioned device of profit carries out a method for correcting error in hole, comprises the following steps:
A () is carrying out in diaphragm wall slotted eye building course, when finding that in hole, deflection exceedes code requirement, stop creeping into operation;
The deviant at deflection position, skew direction and the degree of depth in (b) measured hole;
C () unloads the wire rope (4) percussive drill connecting and takes out cylinder, be fixed on the bale handle of deviation correcting device;
D () divides into deviation correcting device in hole, lower set direction just to skew direction in hole, side towards in hole, i.e. Deviation rectifier side, opposite side is close to hole wall;
E () slowly descends in hand-hole behind deflection position when deviation correcting device, the wire rope promoting deviation correcting device is fixed on aperture;
F drilling tool is slowly put into hole by (), and measure drilling tool and transfer the degree of depth;
G (), when drilling tool arrives the guiding of deviation correcting device, start interval and impact, by deviation correcting device guide effect, drilling tool can not creep under foramen primum wall direction;
H (), after drilling tool creeps into the Deviation rectifier of deviation correcting device, by the effect of Deviation rectifier, drilling tool can change direction in drilling process, the side of deflection in deflection hole, cutting hole internal cause deflection and outstanding position, reaches the object of correction;
(i) complete rectification work in diaphragm wall unit groove sector hole by said method.
The present invention achieves following technique effect:
Adopt this kind of deviation correcting device to carry out rectifying a deviation in hole, by changing drill bit drilling direction, position outstanding in cutting hole, rectifies a deviation fast, accelerates construction of diaphragm wall progress, ensure that workmanship.
